O que são capacitores de cerâmica? Basta ler este post.

Ceramic capacitors which take ceramic as raw material. Such as high & low dielectric constant capacitors, high & low voltage capacitors. Ceramic capacitors are electronic components used to store electrical charge. They are made by extruding high dielectric constant capacitor ceramic barium titanate, then make titanium oxide into round tubes, discs, or plates, and plating…

O que você não sabe sobre condensadores de cerâmica

Ceramic dielectric capacitors use mainly ceramic as the insulator material, and their basic construction is to overlap ceramic and internal electrodes. There are several types of ceramic materials. Since the consideration of harmless electronic products, especially lead-free, PB (lead) with high dielectric coefficient has been withdrawn from the field of ceramic capacitors, and TiO2 (titanium…

Condensadores de cerâmica tipo chumbo e tipo parafuso de alta tensão, como escolher?

Many high-voltage ceramic capacitor products of the same voltage and capacity have two different shape characteristics: lead type and screw type. So, how to determine which high-voltage capacitor should be used in the application process? We use 5000PF30KV ceramic capacitors Let?s analyze the example for you. For example, a customer wants to design a voltage…

5 diferenças entre capacitores de cerâmica e capacitores eletrolíticos, quantos você conhece?

Capacitors are components that store electricity and electrical energy (potential energy), especially in the current electronics field. At present, there are many types of capacitors, and the more common ones are ceramic capacitors and electrolytic capacitors. So, what are the differences between ceramic capacitors and electrolytic capacitors? First, different dielectric materials Ceramic capacitors are also…

Os capacitores cerâmicos são divididos em 2 classes, como distingui-los?

Class ? ceramic capacitor, which used to be called high-frequency ceramic capacitor, is a capacitor made of ceramic dielectric with low dielectric loss, high insulation resistance and linear change of dielectric constant with temperature. It is especially suitable for resonant circuits and other circuits requiring low loss and stable capacity, or for temperature compensation. Such…

3 vantagens dos Capacitores Cerâmicos de Alta Tensão

High voltage ceramic capacitors are used in power systems. Generally, high-voltage ceramic capacitors are used in products such as power system metering, energy storage, and voltage division.  To understand the advantages of hv capacitors, we must first understand his production process The production process as follows: Grinding powder – tablet pressing – sintering – polishing…

Capacitor de cerâmica de alta tensão com as mesmas especificações, por que os preços dos diferentes materiais são tão diferentes?

Why do high-voltage capacitors of the same specification differ in price by about 10 times due to different materials? The customer told me that a supplier’s quotation for this high-voltage ceramic capacitor is 3.8 yuan. But what you quoted is a high-voltage capacitor made of N4700 material, the price is 42 yuan, why? It turned…

Qual é a diferença entre o dielétrico cerâmico N4700 e Y5T?

1. O condensador de cerâmica feito de material N4700 é um tipo de material cerâmico com boas características de freqüência. É geralmente usado nas ocasiões em que a freqüência é maior que 100KHZ e o ângulo de perda é pequeno (0,0001). Quanto menor o ângulo de perda, menor o aumento de temperatura e menor a atenuação de freqüência da capacidade.

Por que a capacidade dos capacitores de alta tensão decai após um período de tempo de trabalho?

First of all, for example, the N4700 ceramic we use, the temperature drift is about 20%, and it is negative temperature, that is to say, the lower the temperature, the larger the capacity, on the contrary, the higher the temperature rise, the smaller the capacity. In the high frequency and high voltage environment, the capacity…

O que é um capacitor de alta freqüência e alta tensão?

High-frequency capacitors refer to high-voltage capacitors that can operate in high-frequency environments above 1KHZ or for long-term operation in pulse frequency environments.   There are usually two types of high-frequency capacitors: one is high-frequency capacitors, mainly high-frequency circuits represented by non-destructive testing, X-ray machines, CT machines, and the general frequency is between 20KHZ and 200KHZ. …

Quais são os capacitores mais comuns?

  First: ceramic capacitorsCeramic capacitors are made by extruding a high-dielectric constant capacitor ceramic (barium titanate titanium monoxide) into a tube, wafer or disc as the medium, and plating silver on the ceramic as an electrode by sintering method. It is divided into high-frequency porcelain and low-frequency porcelain.High-frequency ceramic capacitors are suitable for high-frequency circuits…

Atenção ao uso de capacitores de cerâmica de alta tensão

First: working voltageWhen using DC rated voltage capacitors in AC circuits or ripple current circuits,Be sure to maintain the Vp-p value of the applied voltage or the Vo-p value including the DC bias voltage within the rated voltage range.If voltage is applied to the circuit, a temporary abnormal voltage may be generated due to resonance…
